TV sometimes turned on standby and turned on and other times it didn't, | I replaced the two 2.2nf capacitors (cq804, cq805) with two 2.5nf and the TV started working normally again components on the cq804 board | heliomar | |

When turning on the TV, it makes a persistent noise and does not turn on, in normal standby mode | Problem in the horizontal circuit short-circuiting the power supply! wsound the power supply goes into protection and starts firing causing the cricket noise | Test the bu1508dx horizontal transistor outside, if you can't test, replace it, if when replacing it it burns out again, possible problem be in the flay back, solution also replace it, before changing the flyback, test if the power supply is supplying the +b range of 100 v and 16 v than in standby and in the 10 v range, and if possible, do a test on capacitor c418 if it is short or has very low capacitance, generally it causes this problem of burning the horizontal o when it shorts out if you buy a new flyback and the problem is the TV turns on and The LED keeps flashing, adjust the screm and focus on the flyback and this problem will be solved, any component that makes up the horizontal circuit shorts out causes this problem, so if you have carried out these tests and replaces and it still persists, carry out a thorough test on the entire circuit horizontal, in my case it was the flyback that is causing this problem solved! Whenever you energize and turn on the TV, the tube charges whenever you move it, remember to discharge it. | Shweize Xz PaTrick |

No image. audio only. | Repair of LED bars. | To avoid feedback... changing the current of the LED bars. I replaced the r765 (2r2) smd with a 6r8 smd (that's what I had on hand. (the best would be 4r7 or 5r6). The 159v voltage dropped to 139v, and the 270ma bar current dropped to 170ma. TV didn't have the original LEDs but they did have LG LEDs). | Eletrônica R-Tec |
